[Healeys] Rear Hub Bearing

[richard mayor]

I doubt that it is a worn bearing. These bearings never seem to wear out. What
usually happens (for whatever reason) is that hub gets loose and the inside
spacer ring (it may be called a "distance piece")  no longer pinches the
bearing properly so that the outer race of the bearing then begins to spin in
the hub. This allows the outer bearing race to grind itself deeper into the
hub. The spacer ring is now useless and the hub can rock. If the bearing has
not gone too deep, you can drive out the studs and machine the face of the
hub. The ring is supposed to stand proud of the hub, with the gasket in place,
about .002" or .003". Check the manual on this for the exact amount. If the
bearing is too deep into the hub then you must replace the hub. You may also
have to use a bearing retaining compound to install the bearing into the hub
as it may no longer be a snug fit.
